Help please tell me why my keys will not work on my laptop.
Try using an external USB desktop keyboard (or a PS2 keyboard, if you have a PS2 jack on the laptop).
If everything works then, your laptop keyboard is malfunctioning. This is usually due to one of three causes:
1. One key is stuck in the "down" or "depressed" position (collapsed/dented silicone cup beneath, or damaged flex legs under key). Look at the keyboard from the side, to see f any key looks lower than the rest (or higher than the rest) Be careful taking it apart to clean and reassemble.
2. Bad ribbon connector, torn, or merely corroded/oxidized keyboard cable connector. This requires opening the laptop to fix. Usually 2-3 screws under laptop labeled as keyboard, allow it to be pried off. Release the cable LOCK, and remove the thin ribbon cable. Reinsert it 5-6 times to clean off contacts, and LOCK the jack again once you are sure it is all snug. If the ribbon was TORN, you will need a new one. Good luck, not easy to find on old laptops.
3. Worst scenario... someone spilled coke (the worst) or beer/beverage inside the keyboard. This eats up the printed oxide connectors, and this cannot be repaired. you will need a new keyboard assembly.. Use a magnifying glass to look between keys, to see if there is stickey, gooey material there. This would be the bad news indicator for number 3.
